One article on using a zinc sulfide to absorb the nickel carbonyl: Nickel Carbonyl Removal.pdf
One article on using a thermal oxidizer to remove the nickel carbonyl: Deposition of Nickel Carbonyl.pdf
Note: none of these articles describe how to recover the nickel carbonyl but rather they discuss destroying it.
EDIT: We decided to not create acetic acid using the process which creates propionic acid as a byproduct due to our wish for propionic acid to be our major product and the process we found creates propionic acid in quantities that are 1% of the quantities acetic acid is made in.
One of the previous standards used involved making propionic acid as a byproduct of acetic acid...these are both possible products on that senior design handout. They are also used in making the same things, so I don't think it would be a bad idea if we looking into making propionic acid from acetic acid and selling them both. If this sounds like a good idea we would need methanol to produce acetic acid...I can do some research on basic info for acetic acid. Mrunal also found info that we can still use ethylene and hydrate it to form acetaldhyde to produce acetic acid and propionic acid as a byproduct. We should look into that too. Thanks

Edit: On the following wiki pages it seems that while the sheet we got in design said that acetic acid was made from methanol it seems that there is a way to use ethylene to make ethanol than oxidize it to make acetaldehyde and from there oxidize it again to get acetic acid all found on the following page:http://en.wikipedia.org/wiki/Ethanol first under the hydration section it discusses the way to make ethanol then under the oxidation section it mentions a way but does not actually show the method to create acetic acid. -Mrunal
just found a link giving details on synthesis of acetic acid from methanol and carbon monoxide. While looking for it I think I came across a website that claimed that this process is a lot more expensive than the newer one, and hence, was altered.
An article regarding the creation of plastics using propionic acid.
To make or buy Ethylene
EDIT: We have now decided to not make the ethylene but instead to buy it. The process we discovered created acetic acid and we decided that to make acetic acid and then to make ethylene was not in our best interests.
Process of making Ethylene from Syngas:
Even though we don't know whether we will be making or selling ethylene this pdf has a lot of important information on producing it from syngas. The important information starts from around the 5th page. Thanks -AlexEthylene from Syn Gas.pdf
240 degrees C optimal temp for hydroformulation
Ethylene pricing information:
The price of ethylene in July 2010 was 29.50-33.25 cents/lb ($650-733/tonne)

Here is the metal we have to use to store the corrosive propionic acid...here is detailed info:

Also heres a link talking about ethylene oxidation and the names of the processes that are used to make acetic acid:

Also, the trend on this site shows that the price for ethylene may be going down: http://www.yarnsandfibers.com/textile-pricewatch/ethylene-price-trends-reports.html, however Japan is thinking of stopping the production of ethylene, so it might affect the price.
